All check-in messages are to be sent to J73W, the callsign assigned to Waitukubuli Amateur Radio Association. Check-ins may be submitted anytime between 0000 and 2359 Eastern Caribbean time each Wednesday. The use of Winlink Express client software is preferred. Messages may be sent by accessing any RMS station (Winlink gateway) that the participant can reach. These are referred to as “RMS Check-ins.” Checkins can be in two formats:
- Plain message format
- (NEW) Winlink check-in form
- The plain message format for a “Standard Check-in” is as follows:
To: J73W
Subject: Winlink Wednesday Check-In
Message body: call sign, first name, city or town, country, (HF or VHF, etc.)
Message body example: J73WA, Wayne, Portsmouth, Dominica (HF)
The format of the message body is important because it is copied and pasted directly into the net roster, which is posted on our website. (see “Net Results,” below).
Check-ins using the Winlink Check-in form is also accepted. The Winlink Check-in form can be found under General Forms in the Standard Template manager. When using the form, click on the “Setup” button and enter “Waitukubuli Amateur Radio Association Winlink Wednesday”, then proceed to fill the form providing the appropriate information. Please note that check-ins, where the mode is not specified, will be categorized as “TELNET”.
On the first Wednesday of each month, check-ins that include a brief weather snapshot on the second line of the message are requested, though not required.
Weather snapshot message body example:
J73YOU, Ron, Marigot, Dominica, (HF)
0841L, Clear, Sunny, Calm Winds, 79°F
On the second Wednesday of each month, check-ins that use an attached Winlink-native IARU radiogram form are requested, though not required.

On the third Wednesday of each month, check-ins that use an attached, Winlink-native ICS-213 form are requested, though not required.

Multiple Check-ins
In an effort to promote the use of both the HF and VHF networks, check-ins on both networks will be treated as separate check-ins. This means that an operator can check-in via HF then check in a second time using the VHF network in his/her area. Check-ins via telnet will only count if the operator does not check-in via one of the radio modes. If the operator checks in via both telnet and a radio mode, only the radio mode check-in will count. It is vitally important that the manner of check-in is clearly indicated in the check-in document. If not, the check-in will be counted as telnet.
